LOCK FOR DRAWERS.

SPECIFICATION forming part of Letters Patent No. 368,697, dated August23, 1887.

Application filed September 27, 1886. Serial No. 214,676. (N 0 model.)

To all whom it may concern: I

Be it known that 1, JOHN EWOLLENsAK, a citizen of the United States,residing at Ohicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Looks for Drawers, of which thefollowing is a specification.

In the drawings, Figure lis a side elevation ofa chest of drawersprovided with my improved locking device, with the drawers unlocked.Fig. 2 is a similar View showing the lock thrown and the drawers locked.Fig. 3 is a sectional View taken on the line a: mof Fig. 2, showing themechanism of the device in operative position; and Fig. 4 is a brokenperspective view of the vertically-sliding bar.

In the drawings, A is the drawer-locking bar; B, a common drawer-lock;O, the bolt of such look; 1), slots in the locking-bar; E, pins or boltswhich pass through the slots D and hold the locking-bar in place, and Fleaves or projections on the locking-bar which project over the edge ofthe drawers when locked.

My invention is intended to be used on bureaus, desks, escritoires,orwherever a number of drawers are used in series; and the object of myinvention is to provide a simple means for quickly and securelylockingall the drawers ofa series with a single key, thereby avoiding theannoyance and expense of a separate lock and key for each drawer.

In applying my invention the locking-bar A is movably fastened to thevertical partition between the drawers,where two rows are used, bymeans, preferably, of the bolts E, which pass through the slots D, andare provided with heads to hold the locking device in place, and to theframe, where only one row is used. Under the end of the locking-bar isacommon drawer-lock, B, so arranged that when the key is turned the bolt0 will raise the locking-bar, and thereby bring the leaves orprojections, whether one or more, up to a positionin front of thedrawers to prevent their being opened, as shown in Fig. 2. The uprightbar and leaves F should not be wider than the vertical partition andhorizontal cross pieces or sills, so that when unlocked, as shown inFig. 1,the drawers may be freely opened. I

What Ielaim as new, and desire to secure &

by Letters Patent, is-

In a drawer-locking device, the combination of avertical externalsliding bar provided with lateral projection or projections moving infront of the drawers, and a lock throwing out an ordinary key-lock boltto vertically move the sliding bar and bring the projection orprojections opposite the face of the drawers to lock the same,substantially'as described.
